Multiple symptoms: Many times when person develop multiple symptoms, they seek one unifying diagnosis. Unfortunately, one cause may not be the answer. Seek an opinion for each problem. I would start with the swollen lymph nodes. The evaluation of swollen lymph nodes may be best addressed by a general surgeon who might need to perform a biopsy to establish an accurate diagnosis.

Mysterious: Sounds like you were exposed to something. See an allergist to see if your various symptoms have anything in common.
